CAN-WASHING MACHINE.

Application filed October 7,

To all whom, 'it may conce-rn.'

' Be. it known that I, CHARLES H. WARREN, a citizen of'the United States, residing at Cathlamet, in the county of lvahkiaknm and State of Washington, have invented ce1'- tain new and useful Improvements in C-anlVashing Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable othersskillcd in the art to which it appertains to make and use thesame.

This invention relates to improvements in One object of the invention is to provide a can washing machine having an improved construction and arrangement of conveying mechanism whereby the cans are brought into position to receive the spraysof Water discharged from the` washing mechanism.

Another object is to provide a machineof this character which will be simple, strong, and durable, eicient and reliable in operation and which will simultaneously wash the inside and the outside` of the cans.

With these and other objects in view, the invention consists of certain novel features of construct-ion, and the combination and arrangement of parts as will be more fully described and claimed.v f

In the accompanying drawings: Figure 1 is a plan view of myimproved can washing machine.v Fig. 2 is a side view thereof. Fig. 3 is a centralvertical longitudinal section of the same taken on the line 3 3 of Fig. 1. Fig. 4 is a vertical cross sectional view taken on the line 4 4 of Fig. 1. Fig. 5 is a similar view taken on theline. 5-5 of Fig. 3.

In the embodiment of the invention as shown in the present instance, I provide a supporting stand or table 1 comprising a top 2 and supporting legs 2. In the top 2 is formed a centrally disposed longitudinal opening 3 and on the lower side of the table top near the ends of said opening are secured shaft bearing brackets 4. Arranged the'ends thereof, is a wire netting cover 5 the edges of which are secured to the top of the table along the edges of thc opening 3 as hown.

Revolubly mounted in the brackets 4 are sprocket gear shafts 6 and 7 on which are ixedly mounted pairs of sprocket gears 8, the hubs 9 of which project inwardly on the shafts and are provided with set screws Specification of Letters Patent.

which engage the shafts vand hold the sprocket gears against turning thereon. The inner ends of the hubs 9 engage and thereby positively hold the gears spaced apart the proper distance. operatively engaged with the sprocket gears. 8 are can conveying chains 11 the upper stretches of which are adaptedto support the cans and to convey the same across the table 1 in positionto receive the sprays of waterejected from the washing mechanism as hereinafter described.

The cans are held in position on and Guided in their movement across the top of the table by pairs of parallel, fiat, can `guiding bars 12v which are arranged along the opposite sides of the opening 3 on the top of the table with their flat faces arranged parallel to the table top and their inner edges ositioned in close proximity to the sides o the cans to be washed. The bars 12 are sup` ported and Yheld in parallel relation one above the other along the opposite sides of the opening 3 by posts or standards 13 which are secured at their lower ends in the top of the table and have arranged thereon upper and lower spacing sleeves leoneI of which is Adisposed between the lower plate and the top of the table, and the other of which is arranged between the upper and lower plates, whereby said plates are spaced apart and held in position on the posts. The u per ends of the posts 13 are threaded and ave screwed thereon clamping nuts 15 whereby the plates 12 and the sleeves 14 are clamped together and firmly held in. position on the posts. Theends of the guide bars or plates 12 are rounded on their ends to facilitate the entrance and passage of the cans between said bars.

the manner described are thoroughly washed on their outer sides by sprays of water which are ejected from and thrown against the outer sides of the cans from pairs of spray pipes 16 which are arranged on the top of the table along and adjacent to the outer edges of the parallel guide bars 12. The pipes 16 are arranged one above the other in parallel relation and are disposed opposite the spaces between the guide bars and between the lower guide bar and the top of the table and have in their inner faces series of water discharging perforations 17 through which the water is forcibly ejected in sprays onto the sides of the cans as they are conveyed across the table in the manner described. The fiat guide bars perform the double function of guides for the cans and means for preventing the water ejected from the pipe 16 onto the cans from splashing and wetting surrounding objects. The pipes 16 are closed on their outer ends by suitable caps and arc connected intermediate their ends to T couplings 18. The cans when moved across the table are washed on their inner faces by sprays of water ejected from a pipe 19 which is arranged below the opening 3 in the table and extends longitudinally at a suitable distance below the screen 5 as shown. The pipe 19 is closed on its outer ends by suitable caps and is connected intermediate its ends to a four-way coupling 2() one member of which is also connected by a short water conducting pipe 21 to the lower T coupling of the pipe 16 on one side of the table while the other member' of the four-way coupling is connected by a short pipe 22 with a T coupling 23 which is connected with the pipes on the opposite side of the table and to which is connected a main water supply pipe 24. By thus arranging the water supply and spray pipes and the plates or bars 16, it will be seen that the water is supplied to all of said pipes and is simultaneously ejected therefrom through the perforations therein thus Washing boththe inside and outside of the cans, at the same time, while they are being conveyed across the table. By arranging the screen cover 6 beneath the upper stretches of the can conveyin chains, it will be seen that the screen Wil effectually support said upper stretches ofwthe cha-ins and the cans carried thereby and assist. in breaking u the jets of Water from the pipe 19 into spray. j

The can conveying chains may be operated in any suitable manner, said chains Having thus described my invention, what I claim is:-

1. A can washing machine comprising a table, can conveying means mounted on said table` laterally' spaced spray pipes arranged on opposite sides of said can conveying means, and fiat laterally spaced can guiding bars positioned to irevent the splashing of the water sprayed rom said pipes onto adjacent objects.

2. A can washing machine comprising a table, can guiding bars vertically spaced above said. table7 a series of vertically spaced can spraying pipes having their' outlets arranged to discharge water beneath said guiding bars, a branch spraying pipe spaced from said table and having its outlets directed to discharge in a direction at right angles to that of the first mentioned pipes, and means for conveying cans past said spraying pipes.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit'- nesseS.
